: Current below normal or open circuit (common for blown bulbs) .
On most Stralis models, you can view active faults directly on the dashboard's display:
: Identifies the type of failure (e.g., open circuit, short circuit). : Shows if the fault is currently active ( ) or inactive ( Common RFC Fault Codes and Meanings
Electronically Controlled Air Suspension (ECAS) sensors and solenoids. Trailer connection sockets (7-pin / 15-pin ISO connectors). Axle load sensors and lift-axle controls. iveco stralis rfc fault codes free
The following table highlights frequently encountered RFC codes reported by drivers and technical manuals: Description Likely Cause / Solution Low air pressure (System 1)
The FMI value following the DTC provides the nature of the failure: : Value above normal range. 03 : Short circuit to positive or high voltage. 05 : Open circuit or low current. 06 : Short circuit to ground. 12 : Value too high or internal component failure. Troubleshooting Steps
: If your air pressure gauge reads zero for the first circuit, the sensor is typically located on top of the Air Processing Unit (Air Dryer) in the middle of the chassis. Grounding Issues : Current below normal or open circuit (common
The acronym stands for Rear Frame Computer . In the complex multiplex electronic architecture of an Iveco Stralis, the vehicle is divided into several electronic control units (ECUs) that communicate with each other via data lines. The Front Frame Computer (FFC) and Rear Frame Computer (RFC) are responsible for controlling various electrical loads on the chassis. Specifically, the RFC unit is responsible for monitoring and controlling all electrical functions at the rear of the vehicle —primarily the entire rear lighting system.
Many veteran drivers and mechanics have compiled troubleshooting spreadsheets and PDFs. By consulting truck mechanic communities like the Iveco Support Forum, you can search for your exact code combination (like RFC 15 02 ) to find out exactly what other drivers did to resolve the problem. Troubleshooting Common RFC Fault Codes
This is the most common error, indicating the instrument cluster has lost contact with the RFC node. Often caused by water ingress, CAN-bus wiring issues, or a dead node. Trailer connection sockets (7-pin / 15-pin ISO connectors)
Disconnect both truck batteries for at least 15 minutes to reset the ECU memory. When to Seek Professional Service
If you have fixed the physical issue (e.g., replaced a broken wire or bulb) but the code remains locked as active or causes a dashboard warning warning, you need to clear the memory.
Water ingress in the 7-pin or 15-pin Susie coils, bent pins in the electrical sockets, or blown bulbs on the trailer.
